Description

Technical Field

[0001] This utility model relates to the technical field of building material drying boxes, specifically a building material drying box with uniform heating. Background Technology

[0002] In the production, processing, and construction of building materials, drying is a key process to ensure the performance and stability of building materials in subsequent use. Common building materials such as precast concrete components, gypsum board, tiles, and wood need to be dried to remove excess moisture after molding or when they are damp. Otherwise, they are prone to cracking, deformation, and mold growth during storage or use, and may even affect the strength and durability of the building structure. Therefore, efficient and uniform drying equipment is one of the core requirements for large-scale production and quality control in the building materials industry.

[0004] However, this patent also has the following shortcomings: the problem with traditional drying ovens is that the temperature distribution is unbalanced. The area near the heat source is prone to local overheating, while the corner areas far from the heat source are not dried enough. For thick-walled building materials, the large temperature difference between the inside and outside makes it difficult for the internal moisture to evaporate effectively, affecting the drying effect. In order to address this situation, a building material drying oven with uniform heating is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a building materials drying box with uniform heating, including a support frame, an outer shell fixedly connected to the upper surface of the support frame, a heat insulation layer fixedly connected to the inside of the outer shell, an inner box fixedly connected to the inside of the heat insulation layer, and a circulation mechanism snapped into the inside of the outer shell, the circulation mechanism including: An air guide channel is provided, with a flow equalization plate fixedly connected to its inner wall.

[0008] According to the above technical solution, the outer surface of the protective door is snapped into the inner wall of the inner box, the air guide groove is snapped into the outer shell and the heat insulation layer, the outer surface of the flow equalization plate is flush with the inner wall of the inner box, and the flow equalization plate is used to disperse the hot air.

[0009] According to the above technical solution, the upper surface of the air guide groove is flush with the lower surface of the infrared heating tube, the upper surface of the return air plate is flush with the upper surface of the inner wall of the inner box, and the flow equalization plate is used to prevent hot air from blowing directly on the building materials, causing local overheating.

[0010] According to the above technical solution, the air guiding mechanism includes a baffle plate, a connecting rod is fixedly connected to the outer surface of the baffle plate, an arc-shaped column one is fixedly connected to the outer surface of the connecting rod, an arc-shaped column two is fixedly connected to the left end of the connecting rod, a synchronous belt drive mechanism and a rotating rod are snapped onto the outer surface of the arc-shaped column two, a rotating sleeve is rotatably connected to the outer surface of the rotating rod, an arc-shaped groove is opened inside the support frame, and the arc-shaped column one is used to indicate the deflection angle of the baffle plate.

[0011] According to the above technical solution, the baffle plate is rotatably connected to the air guide groove, and the connecting rod is rotatably connected to the outer shell, the heat insulation layer, and the inner box. The baffle plate is used to deflect the dispersed hot air at an angle.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This type of building material drying oven with uniform heating, by setting a return air plate, can block hot air when the air is returned through the air duct and introduced into the hot air generator for heat circulation. At the same time, its evenly distributed through holes can guide the airflow to be returned in an orderly manner, ensuring that the airflow rate in each area inside the inner box is consistent, so that the building materials can be continuously and evenly heated during the drying process.

[0014] 2. This type of building material drying oven with uniform heating, by setting an annular baffle, can guide the exhaust direction while continuously expelling moisture from the inner chamber using the exhaust valve, thus preventing the exhaust valve from directly drawing in the high-temperature air inside the air duct. This ensures timely moisture removal and maintains a stable thermal environment inside the chamber.

[0015] 3. This type of building material drying oven with uniform heating uses baffles to guide the hot air before it is dispersed by the flow equalization plate. The adjustable deflection angle of the baffles guides the hot air to diffuse more efficiently to all areas of the inner chamber, avoiding the hot air from being concentrated in only a local area. This ensures that all parts of the building materials can come into contact with the hot air, effectively reducing the problem of uneven heating. Attached Figure Description

[0019] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] Example 1: See Figures 1-4 This utility model provides a technical solution: a building materials drying box with uniform heating, including a support frame 1, an outer shell 2 fixedly connected to the upper surface of the support frame 1, a heat insulation layer 3 fixedly connected to the inside of the outer shell 2, an inner box 4 fixedly connected to the inside of the heat insulation layer 3, and a circulation mechanism 6 snapped into the inside of the outer shell 2. The circulation mechanism 6 includes: An air guide 601 is provided, with a flow equalization plate 602 fixedly connected to its inner wall. An air guide pipe 603 is fixedly connected to the outer surface of the air guide 601. A hot air generator 604 is fixedly connected to the outer surface of the air guide pipe 603. An air guide pipe 605 is fixedly connected to the upper surface of the hot air generator 604. A return air plate 606 is fixedly connected to the lower surface of the air guide pipe 605. An infrared heating tube 607 is fixedly connected to the inner wall of the inner box 4. The infrared heating tube 607 is used for internal heating and drying of building materials.

[0022] A protective door 5 is rotatably connected to the outer surface of the outer casing 2. An air guiding mechanism 7 is rotatably connected to the inside of the air guiding channel 601. A motor 8 is fixedly connected to the upper surface of the support frame 1. A rotating disk 9 is snapped onto the output end of the motor 8. A placement rack 10 is fixedly connected to the outer surface of the rotating disk 9. An annular wind baffle 13 is fixedly connected to the upper surface of the inner wall of the inner box 4. A dehumidification valve 11 is snapped onto the inside of the inner box 4. A filter screen 12 is fixedly connected to the inner wall of the dehumidification valve 11. The filter screen 12 is used to prevent building material debris from being sucked in.

[0023] The outer surface of the protective door 5 is snapped into the inner wall of the inner box 4, the air guide groove 601 is snapped into the outer shell 2 and the heat insulation layer 3, the outer surface of the flow equalization plate 602 is flush with the inner wall of the inner box 4, and the flow equalization plate 602 is used to disperse the hot air.

[0024] The upper surface of the air guide 601 is flush with the lower surface of the infrared heating tube 607, the upper surface of the return air plate 606 is flush with the upper surface of the inner wall of the inner box 4, and the flow equalization plate 602 is used to prevent hot air from blowing directly on the building materials and causing local overheating. When the high temperature and humid air is guided by the annular baffle plate 13, the high temperature and humid air can rise steadily and be discharged after being guided by the annular baffle plate 13 because the center of the connection between the placement rack 10 and the rotating disk 9 is hollow.

[0025] When drying building materials in a traditional drying oven, the temperature distribution inside the inner chamber 4 is prone to imbalance. Areas near the heat source are prone to local overheating, while corners far from the heat source may not be dried properly. Therefore, the circulation mechanism 6 is needed to evenly distribute the heat inside the inner chamber 4 and ensure that there are no blind spots in the airflow inside the inner chamber 4.

[0026] The working principle of this embodiment is as follows: When using the building materials drying oven with uniform heating, the hot air generator 604 intakes and generates hot air. The hot air is guided to the flow equalization plate 602 through the air guide pipe 603 and the air guide groove 601. After being dispersed through the evenly distributed small holes on the surface of the flow equalization plate 602, it enters the inner chamber 4 for preheating. The outer shell 2 and the heat insulation layer 3 achieve temperature insulation with the inner chamber 4. Then, the protective door 5 is opened, and the rack 10 containing the building materials is engaged with the rotating disk 9. The protective door 5 is then closed to seal the inner chamber 4. At this time, the hot air heats and dries the building materials. At the same time, the motor 8 drives the building materials to rotate slowly through the rotating disk 9 and the rack 10. Ensure that the building materials on the surface of the rack 10 are dried evenly; hot air is orderly recovered through the evenly distributed through holes on the surface of the return air plate 606, and enters the hot air generator 604 for recycling through the second air duct 605. The infrared heating tube 607 heats the interior of thicker building materials to assist in drying. When the hot air from both sides passes horizontally through the gaps between the building materials, it will fully absorb the moisture evaporated from the building materials to form high-temperature humid air. The humid air flows towards the top of the inner box 4 under the pull of the return air negative pressure of the second air duct 605. After being guided by the annular baffle plate 13 and filtered by the filter screen 12, it is discharged through the dehumidification valve 11, thereby ensuring that the hot air achieves uniform heating and drying of the building materials in the inner box 4.

[0027] Example 2: Please refer to Figures 5-6Based on Embodiment 1, this utility model provides a technical solution: the air guiding mechanism 7 includes a baffle plate 701, a connecting rod 702 is fixedly connected to the outer surface of the baffle plate 701, an arc-shaped column 703 is fixedly connected to the outer surface of the connecting rod 702, an arc-shaped column 705 is fixedly connected to the left end of the connecting rod 702, a synchronous belt drive mechanism 704 and a rotating rod 706 are snapped onto the outer surface of the arc-shaped column 705, a rotating sleeve 707 is rotatably connected to the outer surface of the rotating rod 706, an arc-shaped groove 708 is opened inside the support frame 1, and the arc-shaped column 703 is used to indicate the deflection angle of the baffle plate 701.

[0028] The baffle plate 701 is rotatably connected to the air guide groove 601, and the connecting rod 702 is rotatably connected to the outer shell 2, the heat insulation layer 3, and the inner box 4. The baffle plate 701 is used to deflect the dispersed hot air at an angle.

[0029] The outer surface of the arc-shaped column 703 contacts the inner wall of the arc-shaped groove 708, and the outer surface of the rotating rod 706 contacts the outer surface of the synchronous belt drive mechanism 704. The arc-shaped column 705 is used to synchronize the deflection angle of the two baffles 701. When the two baffles 701 are deflected synchronously by the synchronous belt drive mechanism 704, the synchronous belt drive mechanism 704 can be pushed out to release the restriction on the two baffles 701. Then, the two baffles 701 are adjusted by the rotating rod 706 and the rotating sleeve 707 respectively, so that they deflect at different angles, thereby adjusting the outflow distribution of hot air inside the inner box 4.

[0030] When drying building materials using a dual-side air intake method, the dual-side air intake positions are located at the bottom of both sides of the inner box, making it difficult to quickly and evenly distribute the heat inside the inner box 4. This can easily cause temperature deviation inside the inner box 4, affecting the drying effect of the building materials. Therefore, it is necessary to adjust the angle of the dual-side air intake through the air guide mechanism 7 to achieve rapid and even distribution of heat inside the inner box 4.

[0031] The working principle of this embodiment is as follows: When using the building materials drying box with uniform heating, when hot air is discharged through the flow equalization plate 602, rotating the rotating sleeve 707 drives the rotating rod 706 to rotate, which in turn drives the arc-shaped column 705 to rotate, and then drives the baffle plate 701 to deflect at an angle via the connecting rod 702; at the same time, the arc-shaped column 703 rotates inside the arc-shaped groove 708, and the deflection angle is the same as that of the baffle plate 701. The deflection angle of the baffle plate 701 can be indicated externally. The synchronous belt transmission mechanism 704 will drive another set of symmetrically arranged baffle plates 701 to deflect at the same angle, guide the hot air inside the air guide groove 601, so that the hot air quickly fills the inner box 4, avoiding the problem of hot air concentration due to a single angle of ejection. At the same time, with the arc-shaped column 703 indicating the deflection angle of the baffle plate 701 externally, it is convenient for the operator to make precise angle adjustment of the baffle plate 701.
